🇵🇱 Poland

Overview

AiPrise verifies Polish businesses against the National Court Register (KRS), the CEIDG register of sole traders and the Central Register of Beneficial Owners (CRBR).

You can also search by legal name.

Statuses and legal forms

Every result carries the register's own status in registration_info.status and an AiPrise status in registration_info.normalised_status. The normalised status is one of Active, Suspended, Dormant, Dissolved / Struck Off, In Liquidation / Insolvency or Unknown.

Register status	Normalised status
AKTYWNA / AKTYWNY	Active
ZAWIESZONY	Suspended
WYKREŚLONY / WYKRESLONY	Unknown
W LIKWIDACJI	Unknown

Legal forms come back in Polish in entity_type, for example Spółka z ograniczoną odpowiedzialnością, Osoba fizyczna prowadząca działalność gospodarczą (sole trader) and Spółka komandytowa.

Quirks and gotchas

Country-specific behaviour to know before you integrate.

Quirk	Details
KRS prefix	A `KRS` prefix in `business_entity_id` is removed before the lookup.
Sole traders need the NIP	Sole traders are in CEIDG, not in the KRS. About 2 in 5 businesses are sole traders; send their NIP.
Struck off shows as `Unknown`	`WYKREŚLONY` (struck off) and `W LIKWIDACJI` (in liquidation) map to `Unknown`. Check the register status before approving.
Board roles are not normalised	The management board president comes back with the role name `President of the Management Board` and the normalised role `UNKNOWN`. Read the role name.
Suspended sole traders	`ZAWIESZONY` (activity suspended) maps to `Suspended`.

Limits

Shareholders are returned only for few companies.
Financial statements come back only for KRS companies that filed them.
